	DETERIORATION (N = 39)	NO DETERIORATION (N = 246)
FACTOR	MEAN ± SD	MEAN ± SD	PROBABILITY*
Age at diagnosis, months	25 ± 14	43 ± 22	P < .0001
Spherical equivalent at diagnosis, D	3.95 ± 1.77	4.39 ± 1.69	P = .15
ET at diagnosis, PD	21 ± 9	19 ± 8	P = .40
	Incidence	Incidence	Probability†
Constant ET at diagnosis	28 (72%)	145 (59%)	P = .18
Fully accommodative ET‡	11 (28%)	117 (48%)	P = .04
Amblyopia during follow-up	19 (49%)	78 (32%)	P = .06
Abnormal distance-near relationship§	16 (41%)	49 (20%)	P = .007
Oblique dysfunction and/or incomitance	17 (44%)	12 (4.9%)	P < .0001

D = diopters; ET = esotropia; PD = prism diopters; SD = standard deviation.

^*t test.

^†Chi-square test.

^‡Orthophoria on distance and near fixation with correction on first follow-up examination.

^§Near esodeviation greater than distance esodeviation by 10 PD or more on majority of examinations.
